RT Journal Article SR Electronic A1 Birošová, Lucia A1 Mikulášová, Mária T1 DEVELOPMENT OF CIPROFLOXACIN RESISTANCE DUE TO CHROMOSOMAL MUTATIONS INDUCED BY 2-NITROFLUORENE JF Biomedical papers YR 2005 VO 149 IS 2 SP 401 OP 403 DO 10.5507/bp.2005.068 UL https://biomed.papers.upol.cz/artkey/bio-200502-0044.php AB In this paper we investigated the ability of 2-nitrofluorene to induce mutations leading to antibiotic resistance in quinolone-sensitive strain Salmonella typhimurium. After preincubation of bacteria with 2-nitrofluorene, the frequency of mutation to ciprofloxacin resistance was 57 fold higher than in the case of spontaneous mutability. Some of resultant resistant colonies showed a great increase of ciprofloxacin MIC.
